Saving money is essential to living life. Everything costs money. Even this wifi? Not free. The device you asked this on? Not free. Saving money is important but why won't people do it? They think its hard, but it's actually easy. Step one, save one cent today, two cents tomorrow, three cents the next day...etc. That leaves you with 365 in the bank if I did the calculations right. Another way you can save is by setting a budget. Pretty easy, but you have to control what you buy and understand that buying this or that could prevent you from buying something else. The last one? Get a job. Preferably a one that gets you a higher pay without actually needing a degree, like a warehouse worker or a waiter.
These methods help you in the best way possible to save money. Good luck!

Given 2x - 9y - 12 = 0, express 5x - 4y + 7 = 0 in terms of x only
olga2289 [7]

Answer:

4 \frac{1}{9}x + 12\frac{1}{3} = 0

Step-by-step explanation:

Based on 2x - 9y - 12 = 0

-9y = 12 - 2x

9y = -12 + 2x

y = -1\frac{1}{3} + \frac{2}{9} x

Therefore...

5x - 4y + 7 = 0

5x - 4(-1\frac{1}{3} + \frac{2}{9} x) + 7 = 0

5x + 5\frac{1}{3}  - \frac{8}{9} x + 7 = 0

4 \frac{1}{9}x + 12\frac{1}{3} = 0

What is the solutions to the equation w/2w-3=4/w
labwork [276]

Answer:

{2, 6}

Step-by-step explanation:

w/2w-3=4/w  is ambiguous.  Did you mean

   w            4

---------- = ------     ?  If so, please enclose "2w - 3" inside parentheses.

2w - 3       w

Cross multiplying, we get w² = 8w - 12.

Putting this into standard form, we get:

w² - 8w + 12 = 0, which factors into (w - 2)(w - 6) = 0.

The solutions are found by setting each factor = 0 separately and solving the resulting equations for w:  {2, 6}.
